To all whom it may concern: v

Be it known that I, EDWARD M. HAcKET'r.

a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have inventedcertain new and useful Improvements in -Boats or Vessels, of which the following is a specification.- This invention relates to im 'rovements in a water craft whether propel ed by steam, wind or otherwise, and for the navigation of still water, such as inland lakes or rivers, or for marine navigation; and it consists in certain peculiarities of the construction, novel arrangement, and operation ofthe various.

parts thereof, as Will be hereinafter more fully set forth and specifically claimed.

The principal object of the invention is to provide a water craft, such as a steam-boat or ship, yacht, sailing vessel, row bo'at or other vessel, for the navigation of water,

which shall be so constructed that the suction or partial vacuum created by the movement of the body of the boat or vessel through and on the water will be practically overcome, so that the progress of the vessel will be greatly facilitated, thus requiring less power to propel it.

A further object of the invention is to so construct and arrange the parts of the craft that an air chamber or cushion will be provided between-its bottom and the water, thus aidin in the support of the boat or vessel or ar ding buo ancy thereto.

Other ob'ects an advantages of the invention will be disclosed in the subjoined description and ex lanation.

In order to enab e othersl skilled in ,the art to which my invention pertains, to make and use the same, I will now proceed to describe it, referring to the accompanying drawing, in which Figure 1 is a vertical longit'udinal sectional view taken on line 1-1 of Fig. 2 looking in the direction indicated by the arrows of a boat or vessel embodying the invention; and Fig. 2 is a bottom plan view of the hull of my improved boat or vessel.

Like numerals of reference, refer to corresponding parts throughout the different views of the drawing.

The reference numeral 5 designates thehull of a vessel which is herein shown as being equipped for propulsion by means of an en ine which drlves a shaft carrying a pro el or or propellers of the ordinary or any pre erred construction. '1he hull 5 may-be made of any suitable size, form and material,"

but is herein shQWn as having. a pointed prow 6 and a roundedand upturned stern .7 with a flat bottom 8 which is provided at its side edges with downwardly depending flanges 9 which extend from the apex -'of the prow 6 to the rear portionof the hull, or .to a point about where the stern begins to extend upwardly' and rearwardl from ;thewater line. The bottom 8 of t ehull is reinforced from the prow rearwardl with a series of transversely disposed 'ollow members 10, all of which, are rounded at their rear ends and most of which are. tapered from their rear ends forwardly, as is clearly shown in Fig. 1 of the drawing.

Extended longitudinally from the front portion of the prow 6 and about midway between the depending flanges or boards 9 is a keel or center-piece '11 which terminates in a forwardly tapered enlargement 12 which is horizontally and lon the rear portion of t e bottom of the hull. The rear art of the enlargement 12 is rovided wita chamber 13 in the rear wal of which is journaled the propeller-shaft 14 transwhich is journaled at its rear end on a verse portion 15 which unites two arallel' bars 16 which are extended rearward y from the rear end of the chamber 13 within the rear ortion of the enlargement 12, as will be" readi y mg.

understood by reference to the drawshown, the propeller-shaft is equipped nary orany' preferred. construction, and has its front end extended intothe chamber 13 which communicates through an opening 18; and a suitable collar or sleeve 19 the hull 5 of the vessel. 3.

Mounted on the upper surface ofth floor tudinally disposed on so with one or more propellers 17 of the ordi- 'or bottom 8 is an 611%1118 20, of any's itable kind or type, on t which is mounted a sprocketsw eel 22which is geared to a sprocket-wheel 23 by means of a chain 24 used for driving the propellershaft. Extended through the floor 8 and one of the transverse members 10 near the prow of the hull are a series of pipes 25 which are preferably extended at their upper ends forwardly, as shown, and each is equip ed with a funnel 26 for the intake of air. he lower end of each of the pipes 25 is rearwardly deflected as at 27 just below the rear end of the member 10 through which they e drivin -shaft'21 of project, yet above the lower edges of the flanges 9, so that they will be. free to supply air to the chambers formed by said flanges and the keel or center-piece 11.

Surrounding the lower and deflected por- 5 tions 27 of the pi es 25 are a series of forwardly tapered s oes or casings 28 which terminate attheir rear ends abruptly, as shown. Extended upwardly in front of the engine 20, then horizontally and then downwardly into the chamber 13, and then through the rear wall of said chamber, is another air-pipe 29 which may or may not have at its upper end a funnel for the intake of air.

- Instead of using a s rocket chain and sprocket-wheels on the riving-shaft of the engine and on the propeller-shaft for driving the latter, it is a parent that said shafts may be geared together in any suitable or wellknown manner. I

From the foregoing and by reference to the drawing it will be readily understood and clearly seen that, as the craft is driven through the water by means of a ropeller or otherwise, the downwardly extending flanges or boards 9 will form an air-chamber to which air will be supplied through the ipes 25,.thus formingan alr-cushion on whic the vessel will ride, and also preventing suction or a artial vacuum in its progress, The air supp ied through the pipe 29 to the rear por-' tion of the chamber 13 will also prevent suc- 1 tion and decrease the vacuity at therear end of the vessel. 4

From the above descri tion and ex lanatlon it is obvious that a oat or vesse constructed accordm to my inventlon 1s susceptible of consi erable modification without material departure from the principles and spirit of the invention, and for this reason I do not desire to be understood as limiting myself to the precise form and arrange ment of the several parts thereof as herein set forth in carrying out my invention'in practice;

Having thus fully described my invention,

, what Ielaim as new, and desire to secure by Letters-Patent, is

-1. In a boat) or vessel, the combination a hull having a longitudinall disposed air-chamber beneath its bottom, 0 a series of pipes communicating at their lower ends with said chamber and extended upwardly from the bottom of the vessel so as to receive air at their up er ends, and a series of transversely dispose hollow reinforcing members on the lower surface of the bottom of the hull within the air chamber thereof.

2. In a boat or vessel, the combination with a hull having on each of the sides 0' its keel longitudinally and rearwardly extended from the bottom of the hull about midway between said flan es and terminatingnear the rear portion 0? the vessel in a forwardly tapered enlargement, a series of pipes located in the front portion of the hull and having their lower ends rearwardly extended withinthe compartments provided by said flanges and kee v 4. Ina boat or vessel, the combination with a hull having a flat bottom, of transversely disposed hollow reinforcing members secured to the lower surface'of said bottom, a

endent flange located at each edge of the bottom, a keel longitudinally extended be tween said flanges and terminating near the rear portion of the vessel in a forwardly tapere enlargement, said enlargement having in its rear (portion a chamber, a senes of pipes locate in the front ortion of the hull and communicatin at their lower'ends with the com artments flormed by the flanges and keel, an another pi 0 extended through and to the rear of the c amber of said enlargement.
